Processing ferrous metal in advantageously, the high-performance grinding wheel as made by cBN have both high speed, it is efficient, high-precision the advantages that.It influences
The case where one key factor of cBN grinding wheel performance is cBN crystal and grinding wheel bond bonding, cBN crystal is viscous in grinding wheel
Knot or fixation can be realized by the physically or chemically connection with binding material.But cBN crystal is difficult to and most of metal, ceramics
The even good infiltration such as resin, keeps the binding force of cBN crystal and matrix poor, has smooth surface and without chemical bonding
With the removing of the binding material of surrounding, cBN crystal becomes exposed, cannot finally be fixed in grinding wheel and deviate from cBN crystal.This
One problem results in cBN grinding wheel can not realize that it is all worth in practical applications, it is therefore desirable to it is coarse to improve cBN plane of crystal
Degree improves the binding force of cBN crystal and matrix to improve the wellability of cBN crystal Yu surrounding binding material.
So far, for increase the method for the surface roughness of cBN crystal be confined to metal coating and with corrosivity it is strong
Acid or highly basic etch cBN plane of crystal.For preparing metal coating method in cBN plane of crystal, it usually needs expensive
Helium can just obtain quality coating as carrying work gas, this method causes at high cost.Using for soda acid etching side
Method, during cBN grains are cleaned through acid or alkaline solution, solution is volatile, at high cost, chemistry discharge work that treated
Difficulty is big, if dealing with improperly, serious pollution will be caused to environment.It is, thus, sought for new cubic boron nitride rough surface
Change processing method, to increase cBN surface roughness, and then improve the binding force of cBN crystal and matrix, enhances cBN grinding wheel in work
Performance in industry application.
